I want something that can sound close to stock (NO DRONE?), but with valves open gets mean. I have a few questions though... your website has a variety of pics, some of them show two separate cylinder mufflers in the back, some show more of a suitcase style. Were the cylinder-style mufflers just a prototype build, and the "suitcase" is the final production version? Does the flow from the two sides of the exhaust mingle inside the suitcase, or is it basically just two separate mufflers and paths contained in a single housing? Secondly - how exactly are you actuating the flaps? You mention "vacuum actuated" in the video... Stock system on the M2 is 100% electronic, not vacuum, and the N55 M2 only has a single actuator stock. I know Remus has a system that basically just uses a "Y" cable, and they supply a second (OE BMW) electronic valve controller. (I have wondered if the stock fuse and wiring are sufficient to handle two valves simultaneously safely...) Are you just using some sort of device that translates between the stock electric connection and pneumatic? (How? You have your own pump and vac accumulator in the kit?) Do the valves in your system still "obey" the OE valve control requests? I ask this because I already have an AWRON gauge, so I can already control my own valve (or set it to auto). I don't want any separate standalone valve control, I just want a system that obeys the stock commands. My only minor gripe is your tip selection; I don't like the separate outer "beauty piece" style. I'd prefer tips that look similar to stock, or possibly rolled angled tips... the floating outer housing doesn't do it for me. I'd also prefer a basic satin black or black chrome over the silly carbon fiber. What size are the outlets, something standard so maybe I can find my own clamp-on tips?

Nuts.
Separate controller = no sale for me. Too bad you couldn't copy Remus' setup. Transfer stock electronic actuator from OE system to one side, and they supply a second OE actuator + "Y cable" to make them work in unison.

As someone that's running a remus exhaust, it really is a great solution. Plug-n-play (with an optional VSC controller to override the valve behavior) is the best.
